BB-Black is a TI AM335X processor-based development platform produced and sold by BeagleBoard.org. BB-Black has excellent graphics performance in the same grade development board, thanks to the AM335X processor set SGX530 graphics engine. Let's take a look at the performance and benefits of this graphics core.
The PowerVR SGX5X series graphics core was designed by ImaginaTIon and was used on the iPhone 3GS and iPhone4 as well as the iPad. The current mainstream embedded graphics cores include ImaginaTIon's PowerVR SGX series, ARM Mali series and Qualcomm Adreno series. The PowerVR SGX530 graphics core used by BB-Black has a 14M/s triangle output rate and a 125M/s pixel fill rate, which is close to the Qualcomm Adreno 200. Some netizens have tested the game performance of the SGX530 under the Android system. The result is a smooth running of large 3D games such as Need for Speed ​​13 and Dungeon Warriors, not to mention 2D drawings of Angry Birds and Fruit Ninja. "".
The PowerVR SGX5X graphics core supports DirectX9, OpenGL2.0 and SM3.0. The core architecture of the core still uses vertex and pixel separation rendering architecture. This more traditional architecture has the advantage of low power consumption and good performance. In addition, it integrates a programmable USSE unit, which eliminates the difference in throughput between vertices and pixel units in a separate rendering architecture, balancing it and ultimately improving collaboration efficiency. The PowerVR SGX5XT also supports a key technology called TBDR, which is designed to save memory bandwidth. TBDR is called TIle-based Deferred Rendering. Its principle is to divide each frame into multiple rectangular regions and perform Z-value check on all the pixels in the region. If you find which pixels are ultimately invisible, then Remove it before entering the rendering. This mechanism massively reduces the number of pixels that are finally rendered, greatly reduces the processing pressure on the system, saves memory bandwidth and space overhead, and objectively achieves the goal of greatly improving performance.
Obviously, BB-Black's integration with the PowerVR SGX530 graphics core, as well as the onboard HDMI high-definition output interface and 512MB DDR3 SDRAM memory, can provide developers with high-performance and cost-effective graphics processing capabilities for a variety of graphics applications. Development is easier and faster.
